Be careful with the vents on these. I had it a bit crammed (though it was still vented), and my capacitors in the power supply died. Was heralded with very weird chirping from the preamps, which would settle down after a few seconds, but the problem gradually got worse.

But it was an easy repair, and it has been working as good as new for the past year or so. Great Australian supplier customer service too (though I ended up just fixing it myself).
